ABSTRACT:
An impact dynamometer is provided to determine a force history that has high and low frequency components. An impact plate receives an impact force at a zone of impact and an accelerometer measures the acceleration of the impact plate at the zone of impact. A plurality of posts, located distally from the zone of impact, support the impact plate and transmit the impact force from the impact plate. One or more accelerometers measure acceleration of the impact plate at the posts. The acceleration measured at the zone of impact and at the posts is indicative of the high frequency components of the impact force. Strain gauges measure the impact force at the posts which is indicative of the low frequency components of the impact force. A spring cushion supports the posts and elastically absorbs the impact force passed through the posts in order to maintain the structural integrity of the impact dynamometer.
